You desperately need a gutter between columns. It's ugly and hard to read in the places where there's a longer line in the left column. If you're concerned about getting as much text onto a page as possible, the font, margins, and (especially) the indents before the numbers in numbered lists all seem bigger than they need to be.
I find the combination of ragged right and two-column very unappealing, at least as implemented here. I might mind less with reasonable gutter space, but overall two justified columns usually look cleaner.
All in all it looks very Microsoft Word-ish. If that really is what you're using, ignore one thing I said above - DON'T ever use what Word calls full justification, because Word is terrible at it. Most DTP programs, on the other hand, can be trusted to do non-hideous justification if your columns are wide enough.
